Extremely weak electron-phonon coupling in Josephson junctions built on InAs on Insulator
Giorgio De Simoni, Sebastiano Battisti, Alessandro Paghi +2
InAs-on-Insulator (InAsOI) enables an effective superconducting proximity effect and extremely weak electron-phonon (e-ph) coupling, allowing precise electronic-temperature control…

Sebastiano Battisti, Matteo Pioldi, Alessandro Paghi +5
We present a groundbreaking demonstration of thermal modulation in a field-effect-controllable semiconductor-superconductor hybrid structure, wherein the heating mechanism is exclu…
Streamline controlled rectification of supercurrent in thin-film asymmetric weak links
Filippo Antola, Sebastiano Battisti, Alessandro Braggio +2
In this study, we examined the supercurrent diode effect (SDE) in mesoscopic superconducting weak links formed by asymmetric Dayem bridges. These planar metallic constrictions, whi…

Here we demonstrate superconducting Dayem-bridge weak-links made of different stoichiometric compositions of NbRe. Our devices possess a relatively high critical temperature, norma…
Bipolar thermoelectric superconducting single-electron transistor
Sebastiano Battisti, Giorgio De Simoni, Luca Chirolli +2
Thermoelectric effects in normal metals and superconductors are usually very small due to the presence of electron-hole symmetry. Here, we show that superconducting junctions broug…
Gate-control of the current-flux relation of a Josephson quantum interferometer based on proximitized metallic nanojuntions
Giorgio De Simoni, Sebastiano Battisti, Nadia Ligato +3
We demonstrate an Al superconducting quantum interference device in which the Josephson junctions are implemented through gate-controlled proximitized Cu mesoscopic weak-links. The…
